Lusk & Son Attn: Mr. Donald Steffenson Vice President P 0 5~x 2140 Newport Beach, California 92663 Dear Don: As you know, on June 12, 1975, AlanM. Voorhees and Associates was authorized by you to make a traffic generation-traffic impact- traffic capacity study of your proposed mobile home park on Poinsettia Lane in the City of Carlsbad. following documents our findings. This study is now complete and the Your proposed mobile home park is to be located on the north side of Poinsettia Lane west of Interstate 5 (1-5) but east cf the Santa Fe Railroad and Carlsbad Boulevard (Old 101). Poinsettia Lane has an interchange with 1-5 but is deadended on.the west before it crosses the railroad, and on the east, at Lagoon Lane. In the future, it is planned that Poinsettia cross the railroad and inter- sect Carlsbad Boulevard on the west, and be extended to El Camino Real and Alqa Road on the east. At the present time, . The existing Poinsettia Lane, as constructed in the vicinity of 1-5, is about one-half of its ultimate width. freeway is also only one-half of the ultimate. of the freeway does not cross the railroad to Carlsbad Boulevard, the City of Carlsbad has expressed concern that there will not be adequate capacity to serve both the existing Sequoia Pacific Mobile Home Park and the new Lusk Mobile Home Park. determining the adequacy of the existing external traffic facilities to serve - both mobile home parks via the 1-5 interchange only. The bridge over the Since Poinsettia west Our study will address itself towards In order to have the very latest existing traffic and generation data from the existing Sequoia Pacific development and other land uses in the area, Alan M. Voorhees & Associates conducted a five hour manual traffic count at the west 1-5 ramp and Poinsettia Lane intersection, on Friday, June 20, 1975 from 12:30 to 5:30 PM. The results of that count are shown below for the total five hours and for the peak hour of 3:30 to 4:30 PM.: WASWI~lGlOPI. D.C. I LONDOW I HONOLUIU I DEfIVER I 09LAN00 I TORONTO I ST.

By equating the above traffic count to these existing units, it can be seen that they are generating-attracting traffic at the rate of 1.73 two-way trips per unit in five hours or .93 per unit inbound and .80 outbound. In the PM peak hour the rate is .27 per unit inbound and .20 per unit outbound. By using the above factors, and an average factor for total two- way daily traffic per unit as derived from 11 mobile home parks scattered throughout San Diego County, the following table of generated traffic from both mobile home parks as planned west of 1-5 can be calculated : I.

This is a very low daily volume of traffic on a street as wide as this’is at the present time. many streets and roads in the region that are carrying much more traffic than this on the same, or a narrower, cross section. As a reference, in Carlsbad, Palomar Airport Road east of El Camino Real is carrying 5500 daily vehicles. There are Since the number of daily vehicles is a poor measure of congestion or capacity, traffic engineers usually.look at peak hour volumes and capa- city as a much more valid yardstick against which to measure existing or future congestion. and out a5 shown in the table, and dividing them in the same manner as the existing volumes shown on Figure 1, and by doubling the existing traffic that is not associated with the mobile home park, a future esti- mated intersection peak hour can be derived as shown on Figure 2: Therefore, using the future peak hour totals in Mr. Donald Steffenson John D.

As was shown above in the future peak hour and in the future dpily traffic analyses, Poinsettia Lane itself and also its intersection with the 1-5 west ramps, will not be close to capacity when both mobile home parks as proposed west of 1-5, are at full occupancy. traffic viewpoint, the City of Carlsbad can therefore approve the John D. Lusk & Son mobile home park, with full assurances that there is more than adequate existing street capacity to accomodate the d eve1 o pme nt . From a , Mr. Donald Steffenson John D. Lusk & Son 465.072 24 June 19’75 Page 5 It also should be pointed out that from a street capacity viewpoint, the extension of Poinsettia Lane over the railroad, to Carlsbad Boulevard, is of doubtful value to the mobile home park under consideration. It is true that some mobile park traffic would be able to go west to Carlsbad Boulevard. However, it is felt that the majority would still use the 1-5 interchange and, in addition, through traffic from Carlsbad Boulevard would. also be able to use Poinsettia Lane to and from the freeway. Probably the new through traffic would more than offset the mobile home traffic since the freeway is still the quickest and best way to most destinations in the North County area.
